China Magnesium Die Casting Parts Suppliers


Now every country optimistic about the prospect of the magnesium alloy die castings,especially in auto,aviation,telecom,transportation and mechanical industry,

which adopt to use magnesium alloy die casting to replace steel casting for reducing weight effectively and then can save energy and reduce environment pollution. The car can decrease 0.4L oil consumption per kilometer if it can relieve every 100KGS. So America,Japan and European countries have enlarge use of magnesium alloy Die Casting Parts, for example, steering wheel, instrument panel, seat skeleton, crankcase, gearbox shell, wheel hub and so on. So magnesium alloy die castings grows at 20%~30% a year, 80% of them are die casting parts. Meanwhile magnesium alloy die castings expand use in appliance light industry and daily hardware, such as notebook shell, VCR box, mobile phone, power tool shell,camera shell, upholstery, mower shell etc. These magnesium alloy die casting parts with a series of advantages, not only greatly reduce weight, but also have the precise & steady dimension and smooth finish surface.


Die-cast magnesium alloy material:
Magnesium and aluminum have big differences in the chemical, physical properties, mainly in terms of chemical reactivity, surface oxidation of the liquid metal

material tightness, thermal effects during solidification, resistant to electricity chemical corrosion resistance capabilities.
Magnesium has a strong chemical reactivity than aluminum and the metal bath surface can not be formed as dense as molten aluminum alloy oxide protective film

to prevent oxidation reaction to proceed, so magnesium alloy flammable or explosive. Magnesium alloy is also easy to dissolve other metals, including magnesium

alloy severely reduce the ability of anti-electrochemical corrosion of nickel, copper and other elements. In addition, the same volume of liquid aluminum and magnesium alloy during solidification.

Magnesium alloy heat release was significantly lower than aluminum.

Magnesium alloy chemical elements:
Mechanical properties of pure magnesium is very poor, can not meet the requirements of industrial parts of the yield strength and tensile strength. By adding alloying elements can significantly improve the mechanical properties of magnesium, the magnesium alloy`s strength to weight than the titanium alloy in all kinds of alloying and ranked second, open up broad prospects for its application. The effect of alloying element second is to improve the performance of magnesium alloy casting. Pure magnesium have high melting point, poor mobility, high shrinkage. By alloying can reduce the temperature of the liquid, increase liquidity. According to the characteristics of magnesium alloy decreased significantly at temperature above 150degrees Celsius and the strength of the alloy, the third role is to enhance the creep resistance of magnesium alloy.

Magnesium alloy commonly used alloying elements are aluminum and zinc. Alloying of aluminum alloy can improve the strength and casting properties. Zinc can also improve the performance of the alloy casting. In order to ensure the casting performance, the aluminum content should be more than 3% in the die casting magnesium alloy, zinc content is less than 2%. Otherwise it is easy to produce crack.


The commonly used magnesium alloy die-casting material

Magnesium die casting material


Common cold chamber die casting machine injection parts must be improved to meet the needs of the magnesium alloy die casting production as follows:

1) Fast injection speed increased from 4~5m/s to 6~10m/s.

2) Reduce the time of supercharging and build pressure.

3) Improve the injection speed and injection force control.

4) Equipped with a special furnace protection gas device
